I would like to know the best image tool to use for a Dreamweaver homepage site to create a simple three images marquee? Should I use Photoshop, Flash or fireworks? Which application is the simplist way to do this? I am a beginner using Dreamweaver 5.5. Take a look at this site to see what I am trying to do. http://www.eventcouturempls.com/home

The one you linked to uses Flash, but you can easily create one without Flash. Google image slider and you will get plenty. A couple I have used and liked are nivoslider and WOW slider. They both run off jQuery.

To put the slider on a homepage, you will use a combination of Photoshop/Fireworks (for the images) and Dreamweaver to code the slider into your page.
